movies. How would you find the joint relative frequency of being female and
attending an action movie?

229
Female

151
250
Total
204
275
479
A. Divide 99 by 250.
B. Divide 204 by 250.
ООО a
C. Divide 99 by 479.
9
D. Divide 99 by 204.
Answer:
A
Step-by-step explanation:
I didn't learn jrf, but I believe that it is the amount of females that watch action movies divided by the total amount of females.
Amount of females who watch action movies= 99
Total females= 250
So, A seems correct.
The joint relative frequency of being male and attending a drama film, divide 124 by 229.
What is Relative Frequency?The number of times an event occurs divided by the total number of events occurring in a particular scenario is described as relative frequency.
Two things must be understood in order to compute the relative frequency:
Total number of events/trialsA category or subgroup's frequency countAction Drama Total
Male 105 124 229
Female 99 151 250
Total 204 275 479
The joint relative frequency is the frequency in a given category divided by the total number of data values.
Here, The total number of males = 229
and, the number of males that like drama = 124
To calculate the joint relative frequency of being male and attending a drama film, divide 124 by 229.

Answer: 2, 8, 96cm^2, 35 miles
Explanation:What we know:
We need to solve all of the given problemsWe have the information we needWe can use ratios to our advantageHow to solve:
By using our knowledge of ratios and substitution, we can solve these problems.
Process:First problem
Set up ratio 7.5:15
Find GCF (7.5:15)/7.5
Simplify 1:2
Solution: 2
Second problem
Set up equation (x/10) = (6/7.5)
Rewrite (x/10) = (60/75)
Simplify (x/10) = (4/5)
Common denominator (x/10) = (8/10)
Isolate variable [(x/10) = (8/10)]*10
Simplify x = 8
Solution: 8
Third Question
where x represents the new width, y represents the new length, and A represents the new area.
Set up equation A = xy
Substitute A = (2*4)(2*6)
Simplify A = (8)(12)
Simplify A = 96
Solution: 96 cm^2
Fourth Question
Where x represents the unknown length in miles
Set up equation (21:3) = (x:5)
Rewrite in fraction form [(21/3)] /3 = (x/5)
Simplify (7/1) = (x/5)
GCF 5(7/1) = (x/5)
Isolate variable [(35/5) = (x/5)]*5
Solution: 35 miles = x
Answer: 2, 8, 96 cm^2, 35 milesCheck:Problem 1:
If the scale factor is 2, then the area of a square with the side measurement of 7.5 units should be (due to areas being squared) 1/2^2 of the square with the side measurement of 15 units. Let's solve this:
(1/2^2)(15*15) = (7.5*7.5)
(1/4)(15^2) = (7.5^2)
225/4 = 56.25
56.25 = 56.25
Therefore, a scale factor of 2 is correct.
Problem 2:
If x = 8, then 8/10 should equal 6/7.5. Let's solve this:
when x = 8:
8/10 = 6/7.5
0.8 = 0.8
Therefore, x = 8 is a correct solution.
Problem 3:
If a scale factor of 2 creates the new area of 96 cm^2, then the old area of (6*4) should be (due to areas being squared) 1/2^2 of the new area. Let's solve this:
(1/2^2)(96) = (6*4)
(96/4) = 24
24 = 24
Therefore, the new area is 96 cm^2.
Problem 4:
If the houses are 35 miles apart, then 3 in./21 mi. should be equal to 5 in./35 mi. Let's solve this:
(21/3) = (35/5)
7 = 7
Therefore, the houses are 35 miles apart.
To the nearest tenth, what is the area of a circle whose diameter is 4.4 feet?
Use 3.14 for π.
Enter your answer in the box.
ft²
Answer:
15.21= 15.2 when rounded
Step-by-step explanation:
the formula for finding the area of a circle with the diameter is
A= 1/4 × π ×d^2
Answer:
15.21
Step-by-step explanation:
In order to find the area, you must find the radius first.
The diameter (4.4) divided by 2 = radius (2.2)
The area of a circle is pi times the radius squared ([tex]A = \pi r^{2}[/tex]).
In this situation, r, or radius =2.2.
[tex]A = \pi 2.2^{2}[/tex]
[tex]\pi[/tex][tex]2.2^{2}[/tex]= the area, 15.2053084434.
By rounding to the nearest hundredth, you get 15.21. The second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

Answer:
Answer Choice C.
Step-by-step explanation:
I took the test
Erica solved the equation −5x − 25 = 78; her work is shown below. Identify the error and where it was made. (5 points)
−5x − 25 = 78
Step 1: −5x − 25 − 25 = 78 − 25
Step 2: −5x = 53
Step 3: = -5x/-5=53/-5
Step 4: x = -53/5
−5x − 25 = 78
Step 1: −5x − 25 − 25 = 78 − 25 WRONG
- 5x - 25 = 78
- 5x - 25 + 25 = 78 + 25
- 5x = 103
x = - 103/5
x = - 20,6
Answer:
Step-by-step explanation:
−5x − 25 = 78
Step 1: −5x − 25 − 25 = 78 − 25 <== this is where the error was made.
Step 2: −5x = 53
Step 3: = −5x/−5=53/−5
Step 4: x = −53/5
Right steps:
−5x − 25 = 78
Step 1: −5x − 25 + 25 = 78 + 25
Step 2: −5x = 103
Step 3: −5x/−5 = 103/−5
Step 4: x = 103
Step 1 was where the error was, because she subtracted 15 from both sides instead of adding 15, so they cancelled out.

The number a is less than the number b by 1/5 of b. By what part of a is b greater than a? Need help ASAP. Have to get this done in 20 minutes.
Answer:
The number b is bigger than the number a by 1/4 of a.
Step-by-step explanation:
If the number a is smaller than the number b by 1/5 of b, then
a + 1/5b = b.
Thus,
a= b - 1/5b= 4/5,
b= 5/4 a.
Consider the Expression b=5/4a:
b=5/4a= 4/4a+ 1/4a= a +1/4a
This gives that the number b is bigger than the number a by 1/4 of a.

Factor the expression using the GCF.
4m+32
In order to factor this expression, we should divide both terms of this binomial (a polynomial with 2 terms) by 4 (the greatest common factor)
Note:- We usually factor out the Greatest Common Factor, or the GCF.
Divide:-
m
8
Add the terms:-
m+8
Put parentheses around them:-
(m+8)
Put 4 outside the parentheses:-
4(m+8)
notes:-If you wonder whether or not you've factored correctly, you can use the distributive property & distribute :)

The boys track team needs to keep a count of how many laps they run at practice so they know the distance. Each lap is 400 meters. What is the difference between the teammate who ran the furthest and the teammate who ran the least distance?
Answer:
9 laps or 3600 meters.
Step-by-step explanation:
First you want to find who has ran the furthest and the least distance.
So we have Rory ran the most with 14 laps or 5600 meters and Daniel who ran the least with 5 laps or 2000 meters.Next we subtract becuase when you say to "find the difference" it means to subtract.We subtract if you want to find the laps we do 14-5 and if you want to find the number of meters we do 5600-2000.
Hamid's soccer game is 2 hrs. and 15 mins. long. The game starts at 11:00 A.M. The park closes at 6:30 P.M. Each soccer game is the same as Hamid's game. How many more games can be played before the park closes?
Answer:
e
Step-by-step explanation:
Soccer game lasts 2 hours and 15 minutes
The game starts at 11:00 A
The park closes at 6:30
The first thing we need to do is to find when Hamid's soccer game finishes
2 1/4 + 11:00 = 13 1/4 = 1:15
(uh so don't know if this is the correct formula for finding time but the answer is correct)
Guessing that each game lasts 2 hrs and 15 mins, we do the same thing
1.25 + 2.25 = 3.75 = 3 3/4 = 3:45
(i added decimals bc i find it the easiest way for me) 1 game
3.75 + 2.25 = 6 (another game)
The answer is 2 games including Hamid's soccer game.
Hope this helps :)

Step 1: Find the area of the rectangle
Area of a rectangle = base x height
Area of the rectangle = 4 x 10 = 40
Step 2: Find the area of the half-circle
Area of a circle = pi x r^2
---In this case, since we only have half of a circle, we will need to divide the area by 2 (or multiply by 1/2).
---We are also only given the diameter here. The radius of a circle is half of its diameter, therefore the radius of this half-circle is 5.
Area of the half-circle = (pi x 5^2) / 2 = (3.14 x 25) / 2 = (78.5) / 2 = 39.25
Rounded area of the half-circle = 39.3
Step 3: Find the area of the figure
Now that we know both parts of the figure, all that's left to do is add them together to find the total area.
40 + 39.3 = 79.3
Answer: 79.3
